I J r., a citizen of the United States, residin at Sharon, in the county of Walworth an State of Wisconsin, have'invented certain v new and useful Improvements in Fountain- Pens,-of which the following .is aspecification.

This invention relates to improvements in fountain pens, and has for its principal object to [provide an article of thisclass, whereby the ink may be prepared within the storage portions of the pen, to the end, principally, that the usual inconvenience attending the operation of filling may be avoided. i

In the use of ordinary fountain pens, filling the ink reservoir is generally inconvenient, and the ink often becomes thickened unless the penis frequently used. 7,

. One ofthe objects of the invention is to provide a pen of this class so constructed that water may be containedin the ink reservoir, the ink being conveniently and read ily prepared therein at any time when desired, the handling of liquid ink, therefore, being dispensed with, the usefulness of the several parts of the pen not being impaired by periods of disuse, and necessity of frequently cleaning the parts of the pen being obviated.

The invention consists, broadly, of the employmentof a tubular liquid container provided with a pen point, a chamber for storageoo-fan ink-powder, and means to deliver .to the-liquid container-a measured quantity of .theipowde'nf. I

With theabove mentioned objects in view the invention'presents a novel construction,- combination and arrangement of arts as de-' scribed herein and claimed, an as illustrated 'in the drawing, it being understood that changes inform, size,- proportion and. minor details ma be made within the scope of the claims wlthout departing from-the spirit. of the invention or sacrificing any of its-advantages.

. In the? accompanying drawing'Figure 1 is a longitudinal sectional view of 'aafountain' pen illustrating one embodiment of myinvention. Fi 2 is a broken away view of v thes'ame devlce shown in Fig. 1, parts-there-.

flofbeing'in section, the'hood being-in a low-' ere'ol position, the recess got the aplunger be-' mg within-the. liquid receptacle. Fig. 3.

illustrates a modified form; of the invention, the cbmpression means being a spring instead of a screw, for causing a reliable seating or bearing of the plunger head upon the partition. Fig. 4 is a plan view of the cap or hood for clearly showing its angular aperture. Fig. 5 is a plan or end view of the i plunger, and Fig. 6 is a View of its keeper.-

Referring now to the drawing for a more particular description, numeral 1 indicates a fountain pen, consisting in part of a liquid reservoir 2, the same being 1 formed'by the tubular casing 3 and provided with the pen point 4; and any suitable feeding device may be employed and connected with the pen point so that the contents of reservoir -may reach the pen.

At 5 is indicated an ink-powder chamber or reservoir. The powder used. is composed of very .fine granules. It is notexpensive, comparatively, and is prepared ready for use in a dry condition. A quantity equal in volume to a small hazel nut is suflicient for preparing a pint of writing fluid of any de- 9 as a holder for casing 3 slidably mountedthereinand removable therefrom.

At 10 is indicated a hood or cap-adapted to overhangqthe open, outertermina'l of easing 6, the rim 11 of said hood circumscribing said casing, It will be understood that the ink-powder isv contained within chamber 5, and any suitable means'mayb'e employed for-discharging a small;or meas- .ured quantity of the powder from chamber '5 to chamber 2, and at that time preventing the liquid within chamber 2'ffrom entering chamber 5, the means illustrated by Figs. 1 and 2- being a plun er-12 removablymounted within the angu ar. aperture 13 (Fig. 4), the plunger preferably having facets I4 correspondin walls of said aperture, said plunger having a contactrhead 15 for a bearing upon partition 7 and a recess lfi adjacent to said head.

- When the parts are ger may be passed through the aperture of the partition; A supply of ink-powder is at formed at its upper end to register with the assembled, the plun- .timedeposited in chamber 5.. f The li outer end of the plunger is then seated inin Fig. 2, and as is apparent, the contents of recess 16 will thereby be conveyed to chamber 2. The lower part of the plunger, preterably, has a threaded connection with partition 7 as shown in the drawing. It will be noted that partition 7 has a thickness greater than the length of recess 16, and the threads of the plunger are therefore in en-- gagement with the threads of the partition while the recessed part of the plunger is passing within chamber 2, and this feature tends to prevent the passage of liquid within chamber 5. However, it chamber 2 is not completely filled, this threaded connection may be dispensed with.

The cap or hood 10 has a threaded connection with the upper end of easing 6, the interior threads of the hood'being indicated at 18, and by manually rotating the hood, plunger 12 may-be elevated so that head 15 will have a bearing upon the partition, as shown in Fig. 1, to-the end that the powder within chamber 5 may be kept in a dry condition.

The principal object for providing the angular opening in the cap, and the corresponding angularly formed walls for the upper terminal of the plunger, is to provide a reliable holding means for the plunger at the time the hood is rotated.

The parts shown in Fig. 3 are substantially the same as already described, the means for operating the plunger 12, however, being more rapid. A spring 19 is employed, the samebeing seated between the hood 10 and the upper end of easing 6', the operation of said spring normally holding head 15, preferably oi" rubber, in contact with partition 7 the wall 11 of the hood being slidably seated upon the wall of casin 6. A

TVhen the hood is manually depressed the spring will contract, head 15, leaving its seating and passing within chamber 2 recess 16 of the plunger passing through aperture '8 and discharging a small measured quantity of the powder within chamher 2. In the use of this modified form of the device, container 2 should not be com-. pletely filled with water, and the powder should beconveyed or discharged while the device is in a Vertical position, but the bearing of head 15 upon the partition effectually prevents liquid from entering within chamber 5 after spring 19 has been released.' 1 i I may, and preferably shall in some in- ;/stances -employ a concentrated ink in semi fluid or liquid form in lieu of the ink-powder mentioned, but the operation of the parts as shown will remain the same as already described.

The device provides a very convenient article for general use. Concentrated material may be carried within the storage reservoir sufficient for months or years of use without replenishing; and afresh, economical supply of ink may always be available by use of water, and settling or thickening of the ink may be avoided.

Having described my invention, what I claim and desire to secure by Letters Patent is,

1. A fountain pen comprising an inkpowder reservoir, a tubular water-container removably mounted upon the reservoir and provided with a pen point, and devices for discharging a portion of the ink-powder from said reservoir to the tubular watercontainer.
